Environmental Protection Agency (EPA).
On January 24, 2006, EPA published a proposed approval of a revision updating the Long-Term Strategy of the State Implementation Plan (SIP) for Class I Visibility Protection, which was submitted by the Governor of Colorado with a letter dated March 24, 2005. In a February 13, 2006, letter EPA received adverse comments on our proposed approval from Rocky Mountain Clean Air Action. In this final rulemaking, we address the adverse comments received and finalize our approval.
Effective Date: This rule is effective on December 4, 2006.

Section 169A of the Clean Air Act (CAA), 42 U.S.C. 7491, establishes as a National goal the prevention of any future, and the remedying of any existing, anthropogenic visibility impairment in mandatory Class I Federal areas  (referred to herein as the “National goal” or “National visibility goal”). Section 169A called for EPA to, among other things, issue regulations to assure reasonable progress toward meeting the National visibility goal, including requiring each State with a mandatory Class I Federal area to revise its SIP to contain such emission limits, schedules of compliance and other measures as may be necessary to make reasonable progress toward meeting the National goal (see CAA section 169A(b)(2)). Section 110(a)(2)(J) of the CAA, 42 U.S.C. 7410(a)(2)(J), similarly requires SIPs to meet the visibility protection requirements of the CAA.
We promulgated regulations that required affected States to, among other things, (1) coordinate development of SIPs with appropriate FLMs; (2) develop a program to assess and remedy visibility impairment from new and existing sources; and (3) develop a long-term (10-15 years) strategy to assure reasonable progress toward the National visibility goal. See 45 FR 80084, December 2, 1980 (codified at 40 CFR 51.300-51.307). The regulations provide for the remedying of visibility impairment that is reasonably attributable to a single existing stationary facility or small group of existing stationary facilities. These regulations require that the SIPs provide for periodic review, and revision as appropriate, of the Long-Term Strategy not less frequently than every three years, that the review process include consultation with the appropriate FLMs, and that the State provide a report to the public and EPA that includes an assessment of the State's progress toward the National visibility goal. See 40 CFR 51.306(c).
On July 12, 1985 (50 FR 28544) and November 24, 1987 (52 FR 45132), we disapproved the SIPs of states, including Colorado, that failed to comply with the requirements of the provisions of 40 CFR 51.302 (visibility general plan requirements), 51.305 (visibility monitoring), and 51.306 (visibility long-term strategy). We also incorporated corresponding Federal plans and regulations into the SIPs of these states pursuant to section 110(c)(1) of the CAA, 42 U.S.C. 7410(c)(1).
The Governor of Colorado submitted a SIP revision for visibility protection on December 21, 1987, which met the criteria of 40 CFR 51.302, 51.305, and 51.306 for general plan requirements, monitoring strategy, and long-term strategies. We approved this SIP revision in the August 12, 1988 Federal Register (53 FR 30428), and this revision replaced the Federal plans and regulations in the Colorado Visibility SIP. The Governor of Colorado submitted a subsequent SIP revision for visibility protection with a letter dated November 18, 1992, which we approved on October 11, 1994 (59 FR 51376).
After Colorado's 1992 Long-Term Strategy review, the U.S. Forest Service (USFS) certified visibility impairment at Mt. Zirkel Wilderness Area (MZWA) and named the Hayden and Craig generating stations in the Yampa Valley of Northwest Colorado as suspected sources. The USFS is the FLM for MZWA. This certification was issued on July 14, 1993. Emissions from the Hayden Station were addressed in the State's August 23, 1996 Long-Term Strategy review and revision (see 62 FR 2305, January 16, 1997). Emissions from the Craig Generating Station were addressed in the State's April 19, 2001 Long-Term Strategy review and revision (see 66 FR 35374, July 5, 2001).
The State conducted its next complete periodic review and revision of the long-term strategy in 2002. With an April 12, 2004, letter, the Governor of Colorado submitted that revision to the Long-Term Strategy of Colorado's SIP for Class I Visibility Protection, which we approved on August 1, 2005 (70 FR 44052).
II. March 24, 2005 Submittal
With a March 24, 2005 letter, the Governor of Colorado submitted a revision to the Long-Term Strategy of Colorado's SIP for Class I Visibility Protection, contained in Part II of the November 18, 2004 document entitled “Long-Term Strategy Review and Revision of Colorado's State Implementation Plan for Class I Visibility Protection.” This revision was made to fulfill the requirements to periodically review and, as appropriate, revise the Long-Term Strategy.
The SIP revision is contained in Part II of the November 18, 2004 document entitled “Long-Term Strategy Review and Revision of Colorado's State Implementation Plan for Class I Visibility Protection.” Part II, “Revision of the Long-Term Strategy,” incorporates by reference requirements for the Hayden and Craig Generating Stations, including emissions limits and schedules of compliance, as previously approved by EPA on January 16, 1997 (see 62 FR 2305) and July 5, 2001 (see 66 FR 35374). Part II also contains explanatory provisions and analyses that are required by section 169A of the CAA, Federal visibility regulations (40 CFR 51.300 to 51.307), and/or the Colorado Visibility SIP. These requirements address existing impairment, ongoing air pollution programs, smoke management practices, prevention of future impairment, and FLM consultation and communication.
We reviewed the SIP revision and determined it adequately demonstrates that the State is making reasonable progress toward the National visibility goal as required by 40 CFR 51.306. Therefore, on January 24, 2006 (71 FR 3796), EPA proposed approval of this SIP revision.
In addition, Appendix B of Part II of the November 18, 2004 document entitled “Long-Term Strategy Review and Revision of Colorado's State Implementation Plan for Class I Visibility Protection,” contains an update of Section XIV, Visibility, of Part D of the Colorado Air Quality Control Commission Regulation No. 3 (Stationary Source Permitting and Air Pollutant Emission Notice Requirements). Although this section has not changed substantively since it was last incorporated into the Visibility SIP (see 53 FR 30431, August 12, 1988, and 59 FR 51379, October 11, 1994), it has been recodified. Therefore, on January 24, 2006 (71 FR 3796) for clarification purposes, we also proposed approval of this recodified version of the State's visibility regulations in order to update the version incorporated into the Visibility SIP.
III. Response to Comments
Comment: In a letter dated February 13, 2006, Rocky Mountain Clean Air Action (RMCAA) submitted adverse comments on our proposed approval. Specifically, RMCAA commented that the SIP revision cannot be approved because of an existing provision in the Colorado SIP related to upsets at stationary sources. In RMCAA's view, the “broad exception to air quality standards and limitations” contained in Colorado's upset provision interferes with applicable requirements concerning attainment and reasonable further progress towards attainment of Start Printed Page 64467the National Ambient Air Quality Standards (NAAQS) and other applicable requirements of the Act, including the visibility goals under Section 169A. Although the comments address an existing SIP provision that the State did not submit as part of its Visibility SIP revision, the commenter does not believe that EPA can approve the State's Visibility SIP revision until the existing provision is eliminated or revised.
EPA's Response: Colorado's upset rule is located in the Colorado Common Provisions Regulation, Section II.E., Upset Conditions and Breakdowns. EPA approved the upset rule on May 31, 1972 (see 37 FR 10842). As noted above, the State did not submit any revisions to its upset rule with the Visibility SIP revision we are approving today. Therefore, we are not acting on the upset rule in this action, and our approval of the Visibility SIP revision will not change Colorado's upset rule or its effect on the implementation and enforcement of the Colorado SIP. Also, our approval of the Visibility SIP revision will not interfere with attainment, reasonable further progress, or any other requirement of the Clean Air Act. Colorado's Visibility SIP revision meets the requirements of our visibility regulations. Thus, our approval is appropriate.
IV. Section 110(l)
Section 110(l) of the Clean Air Act states that a SIP revision cannot be approved if the revision would interfere with any applicable requirement concerning attainment and reasonable further progress towards attainment of the National Ambient Air Quality Standards (NAAQS) or any other applicable requirements of the Act. The Colorado SIP revisions that are the subject of this document are consistent with Federal requirements and rules. These revisions were made to demonstrate reasonable further progress toward the National visibility goal, as required by the Act. They do not interfere with the attainment or maintenance of the NAAQS or other applicable requirements of the Act
V. Final Action
We have reviewed the adequacy of the State's revision to the Long-Term Strategy of Colorado's SIP for Class I Visibility Protection, contained in Part II of the November 18, 2004 document entitled “Long-Term Strategy Review and Revision of Colorado's State Implementation Plan for Class I Visibility Protection,” as submitted by the Governor with a letter dated March 24, 2005. We are approving the revision as demonstrating reasonable further progress toward the National visibility goal as required by 40 CFR 51.306.
This rule will be effective December 4, 2006 without further notice.
VI. Statutory and Executive Order Reviews
Under Executive Order 12866 (58 FR 51735, October 4, 1993), this action is not a “significant regulatory action” and therefore is not subject to review by the Office of Management and Budget. For this reason, this action is also not subject to Executive Order 13211, “Actions Concerning Regulations That Significantly Affect Energy Supply, Distribution, or Use” (66 FR 28355, May 22, 2001). This action merely approves state law as meeting Federal requirements and imposes no additional requirements beyond those imposed by state law. Accordingly, the Administrator certifies that this rule will not have a significant economic impact on a substantial number of small entities under the Regulatory Flexibility Act (5 U.S.C. 601 et seq.). Because this rule approves pre-existing requirements under state law and does not impose any additional enforceable duty beyond that required by state law, it does not contain any unfunded mandate or significantly or uniquely affect small governments, as described in the Unfunded Mandates Reform Act of 1995 (Pub. L. 104-4).
This rule also does not have tribal implications because it will not have a substantial direct effect on one or more Indian tribes, on the relationship between the Federal Government and Indian tribes, or on the distribution of power and responsibilities between the Federal Government and Indian tribes, as specified by Executive Order 13175 (65 FR 67249, November 9, 2000). This action also does not have federalism implications because it does not have substantial direct effects on the States, on the relationship between the national government and the States, or on the distribution of power and responsibilities among the various levels of government, as specified in Executive Order 13132 (64 FR 43255, August 10, 1999). This action merely approves a state rule implementing a Federal standard, and does not alter the relationship or the distribution of power and responsibilities established in the Clean Air Act. This rule also is not subject to Executive Order 13045 “Protection of Children from Environmental Health Risks and Safety Risks” (62 FR 19885, April 23, 1997), because it is not economically significant.
In reviewing SIP submissions, EPA's role is to approve state choices, provided that they meet the criteria of the Clean Air Act. In this context, in the absence of a prior existing requirement for the State to use voluntary consensus standards (VCS), EPA has no authority to disapprove a SIP submission for failure to use VCS. It would thus be inconsistent with applicable law for EPA, when it reviews a SIP submission, to use VCS in place of a SIP submission that otherwise satisfies the provisions of the Clean Air Act. Thus, the requirements of section 12(d) of the National Technology Transfer and Advancement Act of 1995 (15 U.S.C. 272 note) do not apply. This rule does not impose an information collection burden under the provisions of the Paperwork Reduction Act of 1995 (44 U.S.C. 3501 et seq.).
The Congressional Review Act, 5 U.S.C. 801 et seq., as added by the Small Business Regulatory Enforcement Fairness Act of 1996, generally provides that before a rule may take effect, the agency promulgating the rule must submit a rule report, which includes a copy of the rule, to each House of the Congress and to the Comptroller General of the United States. EPA will submit a report containing this rule and other required information to the U.S. Senate, the U.S. House of Representatives, and the Comptroller General of the United States prior to publication of the rule in the Federal Register. A major rule cannot take effect until 60 days after it is published in the Federal Register. This action is not a “major rule” as defined by 5 U.S.C. 804(2).
Under section 307(b)(1) of the Clean Air Act, petitions for judicial review of this action must be filed in the United States Court of Appeals for the appropriate circuit by December 4, 2006. Filing a petition for reconsideration by the Administrator of this final rule does not affect the finality of this rule for the purposes of judicial review nor does it extend the time within which a petition for judicial review may be filed, and shall not postpone the effectiveness of such rule or action. This action may not be challenged later in proceedings to enforce its requirements. See section 307(b)(2).Start List of Subjects
